Member Function Documentation

freeze()

TYPO3\CMS\Core\Cache\Backend\FreezableBackendInterface::freeze

(

)

Freezes this cache backend.

All data in a frozen backend remains unchanged and methods which try to add or modify data result in an exception thrown. Possible expiry times of individual cache entries are ignored.

On the positive side, a frozen cache backend is much faster on read access. A frozen backend can only be thawn by calling the flush() method.

Implemented in TYPO3\CMS\Core\Cache\Backend\FileBackend.

isFrozen()

bool TYPO3\CMS\Core\Cache\Backend\FreezableBackendInterface::isFrozen

(

)

Tells if this backend is frozen.

Returns

‪bool
